I'm aware of this other quesion, but it doesn't answer with regards to usb-tethering:
I'm going to use my android phone for tethering, so I can use the connection in my laptop. All following options are available on my phone:
- usb tethering
- bluetooth tethering
However, I would like to know the most efficient method in terms of power consumption. This article tells me that usb is the least expensive and wifi the most in terms of power consumption. Is that true?
